MAIN COMPONENTS OF SPRAYER
CALIBRATING THE MASTERFLOW SPRAY CONTROL
To calibrate the working pressure, proceed as follows:
CABLE CONTROL
01 - Engage the PTO and accelerate gradually until reaching 540 rpm.
02 - Set all levers to turn on the chemical flow . (Fig. A)
03 - Turn the pressure regulator clockwise to increase the pressure in the circuit. Turn it coun-
terclockwise to decrease the pressure in the circuit.
NOTE: As a reference for the calibration, keep the pressure at 60 psi, for example.
ATTENTION : Set the presure regulator needle at the reference pressure to calibrate the boom
sections (Ex. 60 psi).
